Re: A gun is involved in every single mass shooting.
"Just stop right there.... the vast majority of people that have mental health issues do NOT and are not violent."
Actually, it's well known that people who are mentally ill tend to follow the preoccupations of their society. For instance, in the Victorian era religious obsession was a big thing; in the Freudian era mentally ill people tended to become sex obsessed, thus providing circular justification.
So if a society has a significant number of mentally ill people shooting people and blowing things up, what does that tell us?
